Figs.- 7, 8, 9, '10,/ `11 and 12 taken axially of the are views of 'Referring to the drawings, I showy a device having a body or supporting frame 1 risingin the form of a columnand provided with` a laterally extending base or bottom portion 2, which latteris adapted to rest v upon the floor. .A

The column l is preferably made rectangular `in form, as shown in Fig. 6. At

Athe upperend ofthe columnv l is a'table 3 which is to receive and'support the work which is to be operated on by the saw. A

saw 5 is shownl arranged at the upper end ofthe member' 1 so as to operate in conjunction with the table 3, the lwork being placed on the table 3 andthenoperated on by the saw 5.4 f

As a'means for driving or rotating they saw, .I show van electric motor arranged within a casing 6 supported near the-bottom of the device and connected'by a belt 7 with ai pulley 8 (Fig. 5), on the shaft 9 carrying the saw 5. As an arrangement for adjusting I show means by the tightness ofthe belt 7,'

the casing 6 may which the electric motor in be adjusted vertically so may be made more or less tight as desired, to secure the best 'operationof the saw.

As a preferred arrangement, the vcasing 6r 1s lmounted on a movable platform l1 which is shownpivoted upona pivot 12 passing through the lower portion of the column 1, whereby the platform ll'may be swung up and down to give the proper belt adjustment.rv To secure such swingingy movementl and lock the platform in adjustment, I show? 'an adjusting-screw 13 passing` through the platform and fitted into al threaded socket l 14 on the bottom member 2, the upper end of the screw 13 having-a wheel 15 with a shank that 4the belt y7 l ES PA-I EN TT;

or collar 16, so that by rotating the wheel 15 l the screwmay be worked up and down and the collar 16 a'rranged'to act-upon the other l end17 of'said platform', so thatthe latter will be tilted `about the pivotall mounting l2. vThe electrical conductors 18 andl 19 from the'electric'motor are preferably run to a 'cleat 2O on the column 1' and thence into an vinsulating tube 21y and thence out lof the upper end of the same,'and provided at itsl -end with a screwplug 22 to fit'into a wall socket to make connection with an ordinary electric lighting fixture.'-

motor may be employed and a rdirect confk nection made with va building or" factory lighting circuit,*jso"that itisnot necessary y A switch 23" is preferably'employed to control the current tothe motor'. By this arrangementa'small erL to have special electrical arrangements nor necessary to have a transformer nora `fuse device. v This simplifies vand, reduces expense. v

The mounting-"for the sawr 5 vprefer-ably involves -ball bearing arrangements, as shown in Fig. 5, these ball bearings being shown at 25v and 26,y which are arranged at the opposite ends ofthe saw shaft 9. The

ball bearing'25 is arrangedywithi'n a journal member 27v and the ball ybearing 26 within'a journal or bearing28, the members 27 and 28 being preferably extended up from and formed integral with a block 29v secured upon a laterally prov the upper end of the column l.

. The saw 5 is' secured to the lshaft y9 by means of nuts 31 and 32,.` the latter fitting againsta fiangeB- on the shaft 9. The other threaded as'atBl, and provided with a nut jectingy support j 30 wat Lv1w end of the shaft 9 is lreduced andscrewv 35. Collars 36 and 37 are arranged on the shaft l9,0411 opposite sides of the belt pulley 8 and between the latter and the ball bearl 27, and a collar 41 is arranged ings and 26, respectively. A ring 39 is` 46 to *the journali block betweenthe` Other rings secured as by screws ring 39 and ball bearing 25.

42 and 43 are arranged Jutsideof:thefcolfV lars 36 and 37,respectively. The rings 41, 42 and, 43y are providedwith felt'packin'g or the ylili-e fori excluding dust. Ai capor closure 44 isj fitted. into. theI open end of the jiournallbloclr 28, .said meinber44I and block l28 being .correspondingly threaded so as to permit adjustmentof the. member' 441which 'may be accomplished: by providing it with apertures` 45.--45V adapted: toI receive the f prongs of an operating tool.. By this arrangementthe bearings. and1 shaft for the saw maybeifully encased andv protected,-` from dust and -ili-ngsand.- also may! be properly adjusted and -held in' adjustedposition.

- Asian arrangement .for adjusting. ythe work vei'ticallywith'referencetoithe saw, Iprefr erably pivot;` the workztable 3 at'. its rear end, as at 46,A so` that its frontend may beraised andv` lowered toA permit thev work. to be presented to the saw at different heights. The ypivot 46 is,v preferably supported at its opposite -endsby a bracket 471 whose; midy dle portion 48 is secured tothela-teral pro? jection 30by means of bolts-49.

. AS an arrangement for holdingthe, table 3y inany adjusted positionl I. show a link or arm .50fpivotalfly connected at 51 tothe under side .ofl said table and having.' a1 slotted end- 52 adapted tocooperate with a bolt53 having. an adjusting wheel 54. 'By thisv arrangement by looseningt'he bolt. 53 by turnfi ingthe handle54, ft he slotted arm may be released andthe table 3 swungA up. or

' down.- tofany desired position,4 after which thewheel 54 may be again turned toloclry the slotted arm: 50 in theadjusted position, the holt@ fitting intov ak threaded socket 55 on. the member 1' (Fig. 1),.` v The table 3 is shown?. in. a somewhat; elevated position in rig. i.

- the tabley 3` (IT-ige. 3 and 5)'. In this: way

the. gauge 6.0 may' he, moved. backand forth on the tablev towardi and away from the saw,

such moyem-ent being'I directed` by the slide 61 sliding in the recess'or slideway 62. The

giange. 6= isproxnded with aY front upwards lys ending.abutment 64 againstA which the wordt muy rest..y sotliat.y by pushing the gauge member 70.

v forward the workA will be pressed upon and vadvanced by the abutment 64. n

Provision is also made for holding the work against lateral; movement and also for pushingv'it laterally toward the saw, that is ina-direction lengthwise of the member 60. To such end I show a slide arm 65 (Fig. 10),. .which is adapted to slide along the member 60 toward and away from the saw 5.

As an arrangement forpermitting theflateralv sliding movementof the arm 65.vr and for. holding. it in any1-adjusted position, I showmechanism for this purpose partlyf'en the member 60 andlpartly onsaidmember 6.5. SuchA mechanism comprises a rack 66 mounted onthe gauge. GOandhavfillg: teeth 67 on its: rear face, the member 6.5,I being provided with a hookor'. loopfshaped.y por.h

The locking member 69 passesgthrough a screwk 7:1 which fits in the enlarged' screw threaded recess]` inthe outerend of said head 7.2 by which. it. maybe turnedl sogas to adjust it,long-itudinally` ofthe mernher'O.V rlhe outerend, portion of the membery 69 is reduced asat "7131 and! made cylindrical in formso. that A the screw 71.y may. rotate uponi it, andthe outer end. of, said portion 7,3 is provided with a screwv threaded socket adapted to' receive the end. of: a screw 74, the head 7 5 of; vsy'hichis.outside`of= the head 724.. rIlhe end of the memberr 6.9 is toot/hed so that it may grip orengage the teeth 67 on. theraelr 66 and. said member 69L isi provided. withA aylong'itudinal slot adaptedv t0 receive the. endi of: a screw. 7.6wshereby Said member 6.9 may be. slid back. and forth 'to engage and; d isengage, the rack teeth 67 without rotating. The rotation of the memf ber` 72; causesthis: in `and out movement of the member 69. 'Ihn-s thev slide arm 65 may be.engagedwithrand disengaged from the rack` 66y bytunning `the' head or collarl 7g2 in onedirectionor the othery and when: released. may be slidj from-sidetorside of the table 3. along the rack 66.2 to any: desired po.

ber 69 to grip the rack tooth 67. This will give a-,generahY adjustment of thearm. 65-but not an exact adjust-nient of, the` same.

Tosecure such an. exact adjustment I provide an arrangement whichrv the rack 66 may be adjusbech slightly in. a longitudinal manner-intona direction or the other te, a
